The sum of all angles of a quadrilateral is
A quadrilateral having one and only one pair of parallel sides is
How many parts does a triangle have?
The angle of a triangle are in the ratio 2 : 3 : 4. The smallest angle is
2x + 3x + 4x = 180°
Smallest angle = 2x = 2 × 20° = 40°
One of the base angle of an isosceles triangle is 65°. The vertical angle is
Vertical angle = 180° – (65° + 65°)
= 180° – 130° = 50°
Each angle of an equilateral triangle is
An angle measuring 360° is
The measure of a straight angle is
An angle measuring 205° is
If there are 36 spokes in a bicycle wheel then the angle between a pair of adjacent spokes is
The minimum number of points of intersection of three lines in a plane is
Two planes intersect
One of the acute angle of a right triangle is 55°. What is the other acute angle?
Other angle = 180° – (90° + 55°)
= 180° – 145° = 35°
In a ∆ABC, 3∠A = 4∠B = 6∠C. What is the measure of largest angle?
A triangle having sides of different length is called
The angles of a quadrilateral are in the ratio 3 : 4 : 5 : 6. What is the largest angle
3x + 4x + 5x + 6x = 360°
∴ Largest angle = 6 × 20° = 120°
A quadrilateral having two pairs of equal adjacent sides but unequal opposite sides is
A cone has how many vertex?
A brick is an example of
How many vertex a cylinder has?
